Coaxial Adapter Cable Rangeful BNC (male) to PL259 (UHF) RG58 50 Ω, 2 m

Rangeful BNC (male) to PL259 (UHF) coaxial adapter cable on RG58 offers a 2 m flexible connection with 50 Ω impedance for linking equipment that uses BNC and PL259 connectors. The cable is designed for temporary or semi-permanent signal routing between radio, amateur radio, CB and test instruments, providing the familiar handling and electrical characteristics of RG58 coax in a compact, ready-to-use cable assembly.

Advantages

The adapter cable combines a BNC male connector and a PL259 (UHF) connector on a standard RG58 conductor, maintaining typical 50 Ω characteristic impedance to reduce reflections and preserve signal integrity for many RF applications. Its 2 m length gives working freedom without excessive slack, and the RG58 construction balances flexibility and durability for field and bench use. Connectors are fitted to ensure stable mechanical and electrical contact with common BNC and PL259 ports.

Suitable for

• Connecting amateur radio transceivers to equipment with UHF (PL259) inputs
• Linking CB radios to test instruments or antennas with BNC interfaces
• Temporary signal routing in laboratory and bench test setups
• Field use where a short, flexible BNC-to-PL259 conversion is required

Key specifications

• Cable type: RG58 coaxial
• Characteristic impedance: 50 Ω
• Length: 2 m
• Connector A: BNC male
• Connector B: PL259 (UHF)
• Typical use frequency range: VHF and lower UHF bands (dependent on system)
• Construction: stranded center conductor with braided shield

How to use

Align the BNC male connector with the BNC jack and push then twist or snap into place depending on the socket style. Screw the PL259 onto the matching UHF female connector until hand-tight and, if necessary, secure with a suitable wrench for a firmer mechanical connection—do not overtighten. Route the cable to avoid sharp bends or kinks and keep it clear of heat sources and moving parts. For test setups, connect the cable last after other connections are in place to reduce the risk of static or accidental shorts.

Usage recommendations

Inspect connectors before use for damage or corrosion. Use for low- to medium-power RF signals within the cable’s frequency capability and observe proper grounding and antenna safety practices. Replace the cable if the outer jacket is cut, the shield is compromised, or signal loss increases noticeably.
